Step-by-step explanation:

Simplifying

(8x + 9) + -1(6x + -1) = 0

Reorder the terms:

(9 + 8x) + -1(6x + -1) = 0

Remove parenthesis around (9 + 8x)

9 + 8x + -1(6x + -1) = 0

Reorder the terms:

9 + 8x + -1(-1 + 6x) = 0

9 + 8x + (-1 * -1 + 6x * -1) = 0

9 + 8x + (1 + -6x) = 0

Reorder the terms:

9 + 1 + 8x + -6x = 0

Combine like terms: 9 + 1 = 10

10 + 8x + -6x = 0

Combine like terms: 8x + -6x = 2x

10 + 2x = 0

Solving

10 + 2x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-10' to each side of the equation.

10 + -10 + 2x = 0 + -10

Combine like terms: 10 + -10 = 0

0 + 2x = 0 + -10

2x = 0 + -10

Combine like terms: 0 + -10 = -10

2x = -10

Divide each side by '2'.

x = -5

Simplifying

x = -5

Answer:

x = 2

Step-by-step explanation:

[tex]4(2x-5)+15 = 11 => 4(2x-5) = 11 - 15 => 4(2x-5) = -4 => 2x-5 = \frac{-4}{4} => 2x-5 = -1 => 2x = -1 + 5 => 2x = 4 => x = 2[/tex]

The value of x is 2 for equation 4(2x - 5) + 15 = 11

Two or more expressions with an Equal sign is called as Equation.

The given equation is 4(2x - 5) + 15 = 11

Four times of two x minus five plus fifteen equal to eleven

4(2x - 5) + 15 = 11

Apply distributive property on the LHS

8x-20+15=11

8x-5=11

Add 5 on both sides

8x=16

Divide both sides by 8

x=2

Hence, the value of x is 2 for equation 4(2x - 5) + 15 = 11

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Note that there are 16 total marbles. A is simply a set of sequential events. On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375. Event B is translated into 2 events: Blue + (White or Red) or (White or Red) + Blue. The probabilities of each of these events, added together would be (2/16) * (14/15) + (14/16) * (2/15) = 0.2333333333; therefore, A is more probable.

Answer:

130°

Step-by-step explanation:

Answer:

New coordinates of  P' are:  P'(5, -3)

Hence, option B i.e. P'(5,-3) is correct.

Step-by-step explanation:

When a point A(x, y) is rotated 90° clockwise around the origin, we flip x and y and reverse the sign of x.  

Thus,  

The rule to rotate a point A(x, y) after a rotation 90° counterclockwise around the origin is:  

A(x, y) → A'(y, -x)

In our case, the point P(3, 5) is rotated 90° clockwise about the origin. Thus, the coordinates of  P' will be:

A(x, y) → A'(y, -x)

P(3, 5) → P'(5, -3)

Therefore, coordinates of P' are:  P'(5, -3)

Hence, option B i.e. P'(5,-3) is correct.

Answer:

A) 130°

Step-by-step explanation:

Angle UTV = angle YTX = 75°

Angle VTW = 55°

so UTW = 75 + 55

if this helps, please give brainliest if possible

Answer:

A

Step-by-step explanation:

∠ UTV = ∠ YTX = 75° ( vertically opposite angles )

∠ VTW = 55° ( angle at centre is equal to arc that subtends it )

Then

∠ UTW = ∠ UTV + VTW = 75° + 55° = 130° → A
